My invention relates to improvements in anti 1 i I glare devices for attachment to automobile headlights for the purpose of preventing exces sive glare from the direct or reflected rays fromblinding the eyes of drivers in control of approaching vehicles and at the same time-to permit the headlight to maintain its full beam throwing, capacity.

A further object of my invention is to so construct my device that it can be attached many standard headlight in lieu of the standard bezel or rim furnished, and a still further object of my invention is to so construct my device that it willin no way mar*the appearanceof theheadIight-and can be attached without any alterations to the headlight structure apart from the replacing of the bezel. f

A still further object ofmy invention is to utilize the principle of vertical light ray deflecting' vanes or ribspositioned across the headlight lens and to so construct and position my vanes that the anti-glare properties of my in vention will be superiorto this type of device used heretofore.

My invention consists of an anti-glare device constructed and arranged all as hereinafter more particularly described and illustrated in the accompanying drawing in which:

Fig. 1 is a front elevational view of a headlight furnished with my. device.

Fig.2 is a plan view of the headlight shown in.

Fig. 1, and

Fig. 3 is an enlarged horizontal cross sectional view through the forward portion of the headlight shell showing my device attached thereto.

Like characters of reference indicate corresponding parts in the diiferent views in the drawing. Q

The numeral 1 indicates an automobile headlight shell of the standard type, suitably supported upon a bracket which is not shown as it forms no part of the invention; Interiorly of the shell is positioned the parabolic reflector 2 as is usually furnished and 3 indicates the headlight bulb which is positioned in line with the focal point of thereflector. In modern headlight construction, the lens is usually retained in position at the front of the shell 1 by a rim .or bezel of L shaped cross section which extends around the edge of the lens and also around the forward portion of the shell. My device replaces this rim or bezel which is removed.

My invention comprises acylindrical rim or bezel portion 4 which. is adapted to surround the forward portion of the headlight shell and replace the standard rim. The'rim 4 is curved inwardly to a reduced diameter at a. point Sin front of the edge of the headlight shell from where it extends forwardlyin the form of a sleeve or collar 6.

The lens is retained in place "by the inwardly curved reduced diameter por- 'tion 5"of my device "and in'order to provide a dust proof joint I furnish a ring 9 of substari-J tially" L'- shaped cross section which extends around-the'peripheral edge of thelens-a'ndflts between the lens and the portion 5 of my device.

It will thus "be seen that'when my rim 4 is'positioned u on the shell '1 and forced rearwardly into the lock'ed position thatthe lens 7 will be tightly held between my device and the headlight zontal direction; that is, that portion of the sleeve adjacent to the oncoming trailic or passing cars is extended forwardly a greater degree than the portion of the sleeve adjacent to the ditch or the right hand side of the road.

The s1eeve'6 is furnished to carry a plurality of spaced apart vertical vanes 10 which are inclined with respect to the axis of the reflector so that any rays of light striking the faces 11' of thevanes are thrown to the right hand side of the road while other rays extending substantially parallel to the axis of the reflector are projected forwardly in the normal manner. In practice I silver the sides 11 of the vanes 10 in order to secure a maximum reflection and blacken'the sides 12 of thevanes so as to deaden reflection. v The portion of the sleeve. 6 adjacent to the;

that unless they are placed comparatively close together they do notblock the glaring rays from extending to the left hand side of the road or in other words, into the eyes ,of approaching drivers. If the vanes of this type are placed sufficiently close together to out out the blinding rays they have .to be so numerous that they reduce the beam throwing capacity of the headlight. Other contributors to this art have inclined the vanes so that a greater proportion of the light rays are deflected tothe right hand side of the road, but even with this improvement the number of vanes required for satisfactory results were too great not to affect the beam throwing capacity of the headlight.

In experimentation with my invention, I have the drawing The rearward edges of the vanes found that the most satisfactory results are obever, will not be an essential feature in most tained by setting the forward portions 13 of the climates as the heat generated by the headlight vanes at an inclination to be the body portions will be suflicient to melt any moderate amount of the vanes vsouthat glaring rays passing. l e-- 1 snow-.collecting--in;the sleeve; I
